const char_type* _Str
);
Parameters

Example
// char_traits_length.cpp
// compile with: /EHsc
#include <string>
#include <iostream>
int main( )
{
using namespace std;
const char* str1= "Hello";
cout << "The C-string str1 is: " << str1 << endl;
size_t lenStr1;
lenStr1 = char_traits<char>::length ( str1 );
cout << "The length of C-string str1 is: "
<< lenStr1 << "." << endl;
}
The C-string str1 is: Hello The length of C-string str1 is: 5.
